About Dimensional Tolerances in Detailed Drawings
You can set the tolerance standard as ANSI or ISO, and set the tolerance display on or off. You can drive dimensional tolerances using a set of tolerance tables. The system assigns each model a tolerance standard of either ANSI or ISO.
• When you switch from ISO to ANSI, the system assigns the ANSI tolerances based on the nominal dimension’s number of digits and deletes the tolerance table reference.
• When you switch from ANSI to ISO, a set of tolerance tables drives the ISO-standard tolerances.
